Probably my worst was when I knocked myself out cold in the middle of the street, hitting my head getting in a car. It was a pretty serious concussion, as I don't remember it much except for what people tell me. I also couldn't remember appointments or peoples names for a few days after that. There was dried blood in my right ear too, which I found a week later. Evidently, I'm used to driving trucks, and I was moving my ex-GF's Corolla. I guess I forgot for a second that I was getting into a low, little Corolla, and used my leg to launch myself up into it as if it were my truck with 6" lift and 40" tires. Next thing I remember is a worker who ran up from a ranch nearby, and offering to call an ambulance. I had no idea how I got there, but I put 2 & 2 together and now kind of remember it, 10 years later.
